Approach: Macro science, with the human outcome as a quiet secondary cue. Palette: C (Natural).

Extreme macro photograph of a halved red onion and fresh celery leaves, the real dietary sources of isorhamnetin and luteolin. The onion's glossy magenta-violet layers and translucent cell walls fill the left two-thirds of the frame, with fine droplets of juice catching the light. A few crisp green celery leaves and a sprig of dried parsley rest in soft focus to the right. Shot at a slight low angle, shallow depth of field, 100mm macro look. Soft morning daylight from a window behind and to the side gives a warm rim light and gentle translucency through the onion layers. The palette is earthy: plum, sage green, and warm wood tones, with one small electric green highlight on a celery leaf edge. The mood is calm, fresh, and quietly curious, with a hint of rest.
